The interview process lasted about a month and consisted of three parts. The first one was a telephone interview with the HR department which lasted about half hour, the second was a video call with the technical team leader and the managing director which lasted about thirty minutes and the last interview was separated in two parts and lasted in total about one hour and thirty minutes. The questions of the second and third interview were mostly related to my technical skills and knowledge regarding the object-oriented principles, architecture patterns and Android programming. The interviewers were very kind and friendly and made me feel really comfortable.
